| 8521173381 | surface impoundment | Method of disposal of some liquid hazardous wastes in a natural depression or human excavation. Many sites have been closed due to the controversial nature of such sites. | | 18 |
| 8521174264 | reuse | Refers to finding ways to reuse products and materials so that they need not be disposed of. | | 19 |
